Title:
PRODUCTION OF STAINLESS STEEL STRIP FOR CLAD MATERIAL
Document Type and Number:
Japanese Patent JP3695063
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce a production cost and to obtain a clad material excellent in joining strength by grinding a steel strip surface with a brush roll after a stainless steel strip after cold rolling is annealed and a oxidized scale is removed and exposing an oxidized film essentially consisting of Cr2O3 to simplify a production process of temper rolling, etc.
SOLUTION: A stainless steel strip S after pickling is dewatered by an inlet side wringer roll 12 of a brush roll grinding device, is washed and then is ground by a brush roll 14. The strip S rear face is supported by a back up roll 15 having a rubber lining, grinding is made wet grinding by a intermediate spray nozzle 16. Grinding chip stuck to the strip S surface after grinding is washed/ removed by an outlet side water spray nozzle 16, the strip S is dewatered by an outlet side wringer roll 18. When the strip S exposing Cr2O3 on a surface is subjected to joining rolling, Cr2O3 is destroyed to produce a newly produced face, joining strength with a clad material is improved.
